    If the triple glazing is anything less than a 44mm unit, it's not worth the extra money.

    Good a-rated double glazing has an overall u-value of between 1.4w/m2k & 1.2w/m2k
    A 36mm triple glazed unit is approximately 1.1w/m2k.
    40mm is aprox 1.0w/m2

    I have Residence9 (100mm 9 chambered frames) & 44mm triple glazing my overall u-value is 0.8w/m2 which is passive standard.

    So a well fitted 28mm dg system is the way to go if you can't get a 44mm system.

    Also a 28mm unit with 6.8 laminated external & 4mm toughened internal, has better sound reducing capabilities than a triple glazed unit.
